RESUMEN

Background: Social circus is a branch of circus that primarily focuses on personal and community development, rather than an elite level of professional artistry required of traditional circus. Social circus engages participants in circus activities such as juggling and acrobatics with therapeutic aims such as building confidence or developing life skills. While there is a growing body of literature around social circus, there is currently limited literature exploring the interface between social circus and occupational therapy theory. Objective: This study is aimed at examining existing examples of social circus for people with disability (via YouTube videos) through the lens of the Model of Human Occupation (MOHO) to consider the link between social circus and contemporary occupational therapy practice. Methods: The study utilised video analysis as the guiding methodology. A two-part qualitative thematic analysis was conducted on transcripts of YouTube video audio and on-screen text, as well as visual analysis of the corresponding imagery. Results: Social circus provides people with disabilities opportunities to actively participate and experience dignity of risk, independence, and autonomy, in a safe and inclusive environment amongst others. As a highly flexible activity (in structure, timing, tasks, outcomes, and environments), social circus accommodated differences in capacities and provided opportunity for the development of skills, both circus-specific and generalisable to everyday life. Social circus allowed people with disability to shape new identities as performers, friends, and members of a community. Conclusion: Social circus offers a unique means for successfully attaining and achieving a wide range of occupational outcomes for people with and without disability across a diverse range of settings. Utilising an occupational therapy lens led to insights around the social circus environments, development of identity and transference of circus skills to everyday tasks and occupations, that were not previously acknowledged in the social circus literature. Our findings support social circus implementation and collaboration within contemporary occupational therapy practice.

RESUMEN

BACKGROUND: This study aimed to develop an education system using DVD video-based teaching materials or web-based learning to reduce sexual violence among teens in Japan. METHODS: During the first stage, June 2018 to March 2019, an education program using DVD video teaching materials was carried out at three high schools and four universities with research consent from the director of the facility. From 1337 high school students and first- and second-year university students, subjects in their teen years were targeted for analysis. A survey was conducted at baseline and after the DVD video teaching. During the second stage, November 2019 to March 2020, web-based learning using improved video teaching materials was developed and carried out. From the adolescents who participated in the web-based learning, subjects in their teen years were targeted for analysis. A survey was conducted at baseline and after the web-based learning. RESULTS: In the first stage, 876 students consented to and participated in the education using DVD video teaching materials and baseline and after surveys (collection rate 65.5%). Among these, the number of respondents in their teens both baseline and after education was 705 persons (valid response rate 80.4%). In the second stage, the number of respondents in their teens both baseline and after education was 250 respondents in their teens who received web-based learning using the improved video teaching materials (valid response rate 87.1%). The improvement effect of the two programs was observed in attitudes that lead to physical violence, attitudes that lead to mental violence, attitudes that promote healthy conflict resolution, and dangerous attitudes that lead to sexual violence from persons in the community or through the Internet. The web-based learning program achieved an improvement of preventive attitudes toward sexual violence. CONCLUSIONS: The education program using DVD video teaching materials or web-based learning may help prevent sexual violence among teens in Japan.

RESUMEN

PURPOSE: Virus epidemics may be mitigated if people comply with directives to stay at home and keep their distance from strangers in public. As such, there is a public health interest in social distancing compliance. The available evidence on distancing practices in public space is limited, however, by the lack of observational data. Here, we apply video observation as a method to examine to what extent members of the public comply with social distancing directives. DATA: Closed Circuit Television (CCTV) footage of interactions in public was collected in inner-city Amsterdam, the Netherlands. From the footage, we observed instances of people violating the 1.5-meter distance directives in the weeks before, during, and after these directives were introduced to mitigate the COVID-19 pandemic. RESULTS: We find that people complied with the 1.5-meter distance directives when these directives were first introduced, but that the level of compliance started to decline soon after. We also find that violation of the 1.5-meter distance directives is strongly associated with the number of people observed on the street and with non-compliance to stay-at-home directives, operationalized with large-scale aggregated location data from cell phones. All three measures correlate to a varying extent with temporal patterns in the transmission of the COVID-19 virus, temperature, COVID-19 related Google search queries, and media attention to the topic. CONCLUSION: Compliance with 1.5 meter distance directives is short-lived and coincides with the number of people on the street and with compliance to stay-at-home directives. Potential implications of these findings are that keep- distance directives may work best in combination with stay-at-home directives and place-specific crowd-control strategies, and that the number of people on the street and community-wide mobility as captured with cell phone data offer easily measurable proxies for the extent to which people keep sufficient physical distance from others at specific times and locations.

RESUMEN

At present, in the field of video-based human action recognition, deep neural networks are mainly divided into two branches: the 2D convolutional neural network (CNN) and 3D CNN. However, 2D CNN's temporal and spatial feature extraction processes are independent of each other, which means that it is easy to ignore the internal connection, affecting the performance of recognition. Although 3D CNN can extract the temporal and spatial features of the video sequence at the same time, the parameters of the 3D model increase exponentially, resulting in the model being difficult to train and transfer. To solve this problem, this article is based on 3D CNN combined with a residual structure and attention mechanism to improve the existing 3D CNN model, and we propose two types of human action recognition models (the Residual 3D Network (R3D) and Attention Residual 3D Network (AR3D)). Firstly, in this article, we propose a shallow feature extraction module and improve the ordinary 3D residual structure, which reduces the parameters and strengthens the extraction of temporal features. Secondly, we explore the application of the attention mechanism in human action recognition and design a 3D spatio-temporal attention mechanism module to strengthen the extraction of global features of human action. Finally, in order to make full use of the residual structure and attention mechanism, an Attention Residual 3D Network (AR3D) is proposed, and its two fusion strategies and corresponding model structure (AR3D_V1, AR3D_V2) are introduced in detail. Experiments show that the fused structure shows different degrees of performance improvement compared to a single structure.

RESUMEN

OBJECTIVES: The main objective was to describe physicians' perception of their knowledge, skill, and safety before and after training to perform videolaryngoscopy while using the Intubox barrier system when managing the airway of a patient with the coronavirus 2019 disease (COVID-19). The secondary objective was to assess the safety afforded by the barrier by means of visually evaluating particle dispersion during intubation. MATERIAL AND METHODS: Single-arm clinical simulation trial. The participants were physicians who received training in both a lowfidelity and a high-fidelity simulation zone. The participants assessed their knowledge, skill, and safety when using the Intubox before and after training using a specially designed and validated questionnaire. Droplet contamination was estimated visually. RESULTS: Twenty-seven physicians with a mean (SD) age of 40 (10.8) years participated; 63% were women. They perceived their knowledge, skill, and safety to be significantly higher after training. Droplet contamination was seen to decrease when airway management maneuvers were done with the barrier in place. CONCLUSION: After simulation training the emergency physicians judged their knowledge, skill, and safety to be greater when they used the barrier during airway management in patients with COVID-19. The combined use of a laryngoscope and the Intubox barrier resulted in less particle dispersion during intubation.

RESUMEN

The aim of this study was the validation of player and ball position measurements of Kinexon's local positioning system (LPS) in handball and football. Eight athletes conducted a sport-specific course (SSC) and small sided football games (SSG), simultaneously tracked by the LPS and an infrared camera-based motion capture system as reference system. Furthermore, football shots and handball throws were performed to evaluate ball tracking. The position root mean square error (RMSE) for player tracking was 9 cm for SSCs, the instantaneous peak speed showed a percentage deviation from the reference system of 0.7-1.7% for different exercises. The RMSE for SSGs was 8 cm. Covered distance was overestimated by 0.6% in SSCs and 1.0% in SSGs. The 2D RMSE of ball tracking was 15 cm in SSGs, 3D position errors of shot and throw impact locations were 17 cm and 21 cm. The methodology for the validation of a system's accuracy in sports tracking requires extensive attention, especially in settings covering both, player and ball measurements. Most tracking errors for player tracking were smaller or in line with errors found for comparable systems in the literature. Ball tracking showed a larger error than player tracking. Here, the influence of the positioning of the sensor must be further reviewed. In total, the accuracy of Kinexon's LPS has proven to represent the current state of the art for player and ball position detection in team sports.

RESUMEN

Current telemedicine and remote healthcare applications foresee different interactions between the doctor and the patient relying on the use of commercial and medical wearable sensors and internet-based video conferencing platforms. Nevertheless, the existing applications necessarily require a contact between the patient and sensors for an objective evaluation of the patient's state. The proposed study explored an innovative video-based solution for monitoring neurophysiological parameters of potential patients and assessing their mental state. In particular, we investigated the possibility to estimate the heart rate (HR) and eye blinks rate (EBR) of participants while performing laboratory tasks by mean of facial-video analysis. The objectives of the study were focused on: (i) assessing the effectiveness of the proposed technique in estimating the HR and EBR by comparing them with laboratory sensor-based measures and (ii) assessing the capability of the video-based technique in discriminating between the participant's resting state (Nominal condition) and their active state (Non-nominal condition). The results demonstrated that the HR and EBR estimated through the facial-video technique or the laboratory equipment did not statistically differ (p > 0.1), and that these neurophysiological parameters allowed to discriminate between the Nominal and Non-nominal states (p < 0.02).

RESUMEN

BACKGROUND: Primary aim of the current randomized controlled trial was to test the effectiveness of the parenting intervention 'Video-feedback to promote Positive Parenting and Sensitive Discipline' (VIPP-SD) in a sample of parents of preschool-aged twins, as well as differential susceptibility to intervention efforts, that is, whether more temperamentally reactive parents would profit more from the VIPP-SD than parents with lower reactivity. METHODS: The sample consisted of 202 families with same-sex twins [N = 404 children, mean age 45 months (SD = 6.81)]. Randomization was done at the family level in a 2:3 ratio, with 83 families (41%) randomized to the VIPP-SD group, and 119 families (59%) to the control group. After two pre-tests in year 1 and year 2 of the study, the VIPP-SD was implemented in the third year, with a post-test assessment 1 month after the five intervention sessions. Parental sensitivity was observed during structured play in which parent and child copied a drawing together in a computerized Etch-A-Sketch paradigm. Parental limit-setting was observed in a 'don't touch' task in which the parent required from the child to abstain from playing with attractive toys. Parents interacted with each of their twins in separate sessions. RESULTS: The VIPP-SD intervention had a positive impact on the level of parents' positive limit-setting in interaction with their preschool twins, and this positive effect was most pronounced when the parents completed at least five intervention sessions. However, the intervention did not enhance parental sensitivity during structured play. Parents with higher reactivity were not more open to the impact of the intervention, thus for this temperamental marker differential susceptibility in adults was not supported. CONCLUSIONS: The current study is unique in targeting families with twin preschoolers, providing proof of principle that coaching parents with video-feedback promotes parental sensitive limit-setting to both children. It remains to be seen whether this finding can be replicated in families with non-twin siblings, or other parental susceptibility markers. Trial registration Trial NL5172 (NTR5312), 2015-07-20.

RESUMEN

OBJECTIVE: We developed and investigated the feasibility of a machine learning-based automated rating for the 2 cardinal symptoms of Parkinson disease (PD): resting tremor and bradykinesia. METHODS: Using OpenPose, a deep learning-based human pose estimation program, we analyzed video clips for resting tremor and finger tapping of the bilateral upper limbs of 55 patients with PD (110 arms). Key motion parameters, including resting tremor amplitude and finger tapping speed, amplitude, and fatigue, were extracted to develop a machine learning-based automatic Unified Parkinson's Disease Rating Scale (UPDRS) rating using support vector machine (SVM) method. To evaluate the performance of this model, we calculated weighted κ and intraclass correlation coefficients (ICCs) between the model and the gold standard rating by a movement disorder specialist who is trained and certified by the Movement Disorder Society for UPDRS rating. These values were compared to weighted κ and ICC between a nontrained human rater and the gold standard rating. RESULTS: For resting tremors, the SVM model showed a very good to excellent reliability range with the gold standard rating (κ 0.791; ICC 0.927), with both values higher than that of nontrained human rater (κ 0.662; ICC 0.861). For finger tapping, the SVM model showed a very good reliability range with the gold standard rating (κ 0.700 and ICC 0.793), which was comparable to that for nontrained human raters (κ 0.627; ICC 0.797). CONCLUSION: Machine learning-based algorithms that automatically rate PD cardinal symptoms are feasible, with more accurate results than nontrained human ratings. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that machine learning-based automated rating of resting tremor and bradykinesia in people with PD has very good reliability compared to a rating by a movement disorder specialist.

RESUMEN

BACKGROUND: We compared the intubation skills obtained by novice doctors following training using 3 instruments, the conventional Macintosh laryngoscope (Mac) and 2 types of indirect video-laryngoscopes (McGrathTM-MAC: McGrath (McG) and AirwayScope (AWS)), to determine the most appropriate instrument for novice doctors to acquire intubation skills, especially focusing on visual confirmation of vocal cords, during a 3-day intensive manikin training program. METHODS: Fifteen novice doctors who did not have sufficient experience in endotracheal intubation (ETI) and consented to participate in this study were included. We used AirSim and AMT (Airway management Trainer) manikins. First, an experienced anesthesiologist instructed the trainees on using the 3 instruments for a few minutes. Then, after familiarizing themselves with each device for 10 minutes, the participants attempted ETI on the 2 manikins with the 3 devices used in random order. Intubations with each device were practiced and performed for 3 successive days. We assessed the percentage of glottic opening (POGO) score, successful intubation rate and tracheal intubation time for each participant, with each device, and on each day. RESULTS: In the first manikin, AirSim, POGO scores in the McG and AWS groups were significantly higher than those in the Mac group on all 3 days (P < .0001). The number of intubation failures in the Mac group decreased from 2 cases on day 1, to 1 case on day 2 and zero cases on day 3. There were no failures in the McG and AWS groups on any of the days. With the second manikin, AMT, POGO scores in the Mac group were significantly lower than those in the McG and AWS groups on all 3 days. There were no intubation failures in the AWS group on all 3 days. In the Mac group, the number of intubation failures decreased from 3 on day 1, to 2 on day 2 and zero failures on day 3. In the McG group, there were only 3 failures on day 1. CONCLUSION: The 2 types of indirect video-laryngoscopes (McGRATH and AirwayScope) were demonstrated to be suitable instruments for novice doctors to achieve higher POGO scores in a 3-day intensive ETI training.

RESUMEN

STUDY OBJECTIVE: We measure the effect of video discharge instructions on postconcussion symptoms in patients with mild traumatic brain injury in the emergency department. METHODS: A multicenter randomized controlled trial was conducted in which patients with mild traumatic brain injury were randomly assigned to either intervention (verbal, written, and video discharge information) or control (verbal and written discharge information only). All patients were interviewed 1 week and 3 months from randomization. Primary outcome measure was the Rivermead Post-Concussion Symptoms Questionnaire at 3 months. Secondary outcomes were correct recall, Hospital Anxiety and Depression Scale score, health-related quality of life (12-Item Short Form Health Survey), return visits, and patient satisfaction. RESULTS: A total of 2,883 patients were assessed for eligibility, of whom 381 were included in the control group and 390 in the video intervention group. Difference in mean total Rivermead Post-Concussion Symptoms Questionnaire score between the 2 groups was 0.2 at 1 week and 0.3 at 3 months after traumatic brain injury (estimated effect -0.7; 95% confidence interval -2.1 to 0.7). There was also no difference in Hospital Anxiety and Depression Scale score, recall, 12-Item Short Form Health Survey score, return visits, and patient satisfaction between the control and intervention group. CONCLUSION: Severity of postconcussion symptoms in patients with mild traumatic brain injury did not improve by adding video information to standard care. Also, there was no difference in recall, health-related quality of life, return visits, and patient satisfaction between the control and intervention groups.

RESUMEN

Introduction: Neonatal-perinatal medicine (NPM) providers actively manage medical transports. However, there is wide variation in transport education among fellowship programs. Using the flipped classroom methodology, we developed a video and case-based transport education curriculum. Methods: A national needs assessment identified safety, communication skills, and physiology as the most important aspects of transport management. Three 10-minute video modules and two 20-minute case-based discussions were developed to address this content. Using the flipped classroom format, seven NPM fellows from all three postgraduate years of training took part in the curriculum by individually viewing each video followed by participation in group case-based discussions. Cognitive and affective outcomes were assessed using a knowledge and attitude pretest, individual video module posttests, and a postcurriculum follow-up survey. Results: NPM fellows showed significant improvements in transport knowledge and reported increased confidence in their ability to perform important transport roles. Case discussions were adaptable to learners who had different levels of training and had variable transport experience. Case discussions were successfully executed both in person and by video telecommunications during the 2020 COVID-19 pandemic. Discussion: This transport curriculum addressed a national education gap in NPM fellowship training. Using the flipped classroom methodology, cognitive and affective objectives were achieved by improving knowledge and confidence in transport skills among NPM learners. The video and case-based formats were easily implemented, applicable to multiple types of learners, and adaptable to different environments.

RESUMEN

OBJECTIVE: to characterize the content of Youtube™ videos related to nursing professionals during the COVID-19 pandemic. METHOD: a qualitative study that examined 47 videos on Youtube™ posted between 11/03 and 11/04 2020, which were subjected to thematic analysis. RESULTS: four categories emerged: "the role of nurses in care production during the pandemic", which addresses the management of services and individual care; "Overview of the pandemic from the perspective of nurses in different countries", presenting experiences and encouraging physical distance; "Tributes and motivation to mobilize the category", in addition to targeted tributes, calls for nurses to claim their rights; "Criticisms and demands to improve working conditions", which highlights the insecurity of care provision settings. FINAL CONSIDERATIONS: nursing work conditions in different countries, recognition of the importance of professionals during the pandemic, and claims of the category to improve working conditions were the main content found on Youtube™.

RESUMEN

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by the loss of dopaminergic (DA) neurons in the substantia nigra pars compacta. Gait abnormalities, including decreased arm swing, slower walking speed, and shorter steps are common in PD patients and appear early in the course of disease. Thus, the quantification of motor patterns in animal models of PD will be important for phenotypic characterization during disease course and upon therapeutic treatment. Most cases of PD are idiopathic; however, the identification of hereditary forms of PD uncovered gene mutations and variants, such as loss-of-function mutations in Pink1 and Parkin, two proteins involved in mitochondrial quality control that could be harnessed to create animal models. While mice are resistant to neurodegeneration upon loss of Pink1 and Parkin (single and combined deletion), in rats, Pink1 but not Parkin deficiency leads to nigral DA neuron loss and motor impairment. Here, we report the utility of FTIR imaging to uncover gait changes in freely walking young (2 months of age) male rats with combined loss of Pink1 and Parkin prior to the development of gross visually apparent motor abnormality as these rats age (observed at 4-6 months), characterized by hindlimb dragging as previously reported in Pink1 knockout (KO) rats.

RESUMEN

Remote in-home infant monitoring technologies hold great promise for increasing the scalability and safety of infant research (including in regard to the current Covid-19 pandemic), but remain rarely employed. These technologies hold a number of fundamental challenges and ethical concerns that need addressing to aid the success of this fast-growing field. In particular, the responsible development of such technologies requires caregiver input. We conducted a survey of the opinions of 410 caregivers on the viability, privacy and data access of remote in-home monitoring technologies and study designs. Infant-friendly wearable devices (such as sensing body suits) were viewed favourably. Caregivers were marginally more likely to accept video and audio recording in the home if data was anonymised (through automated processing) at point of collection, particularly when observations were lengthy. Caregivers were more open to international data sharing for anonymous data. Caregivers were interested in viewing all types of data, but were particularly keen to access video and audio recordings for censoring purposes (i.e., to delete data segments). Taken together, our results indicate generally positive attitudes to remote in-home monitoring technologies and studies for infant research but highlight specific considerations such as safety, privacy and family practicalities (e.g. multiple caregivers, visitors and varying schedules) that must be taken into account when developing future studies.

RESUMEN

INTRODUCTION: Laparoscopic pyloromyotomy is now an accepted procedure for the treatment of pyloric stenosis. However, it is clear that during the implementation period there are significantly higher incidences of mucosal perforation and incomplete pyloromyotomy. We describe how we introduced a new laparoscopic procedure without the complications associated with the learning curve. MATERIALS AND METHODS: Five consultants tasked one surgeon to pilot and establish laparoscopic pyloromyotomy before mentoring the others until they were performing the procedure independently; all agreed to use exactly the same instruments and operative technique. This involved a 5mm 30-degree infra-umbilical telescope with two 3mm instruments. Data were collected prospectively. RESULTS: Between 1 January 2013 and 31 December 2017, 140 laparoscopic pyloromyotomies were performed (median age 27 days, range 13-133 days, male to female ratio 121:19). Fifty-five per cent of procedures were performed by trainees. Complications were one mucosal perforation and one inadequate pyloromyotomy. There were no injuries to other organs, problems with wound dehiscence or other significant complications. The median time of discharge was one day (range one to six days). CONCLUSION: Our rate of perforation and incomplete pyloromyotomy was 1.4%, which is equivalent to the best published series of either open or laparoscopic pyloromyotomy. We believe that this resulted from the coordinated implementation of the procedure using a single technique to reduce clinical variability, increase mentoring and improve training. This approach appears self-evident but is rarely described in the literature of learning curves. In this age of increased accountability, new technologies should be incorporated into routine practice without an increase in morbidity to patients.

RESUMEN

OBJECTIVE: to analyze YouTube videos with information about COVID-19 in Brazilian sign language. METHODS: a cross-sectional study conducted with 402 videos from the YouTube sharing platform. Chi-square, Fisher's exact, Mann-Whitney and Spearman's correlation tests were used. RESULTS: the videos mainly covered COVID-19 prevention (20.6%). There was a positive correlation between video length and number of views (p<0.001). The length of more than 20 minutes was associated with narration only in BSL (p=0.37) and in BSL with audio (p<0.001), while videos with less than 20 minutes were associated with simultaneous narration in BSL, audio and subtitles. Those with narration only in BSL had a similar number of views to those narrated with subtitles and/or audio (p=0.998). CONCLUSION: the videos were mostly short and included COVID-19 prevention. The longer the video, the greater the number of views. Regardless the presentation of narrations, the videos had a similar number of views.

RESUMEN

Velocity-based training is a contemporary method used by sports coaches to prescribe the optimal loading based on the velocity of movement of a load lifted. The most employed and accurate instruments to monitor velocity are linear position transducers. Alternatively, smartphone apps compute mean velocity after each execution by manual on-screen digitizing, introducing human error. In this paper, a video-based instrument delivering unattended, real-time measures of barbell velocity with a smartphone high-speed camera has been developed. A custom image-processing algorithm allows for the detection of reference points of a multipower machine to autocalibrate and automatically track barbell markers to give real-time kinematic-derived parameters. Validity and reliability were studied by comparing the simultaneous measurement of 160 repetitions of back squat lifts executed by 20 athletes with the proposed instrument and a validated linear position transducer, used as a criterion. The video system produced practically identical range, velocity, force, and power outcomes to the criterion with low and proportional systematic bias and random errors. Our results suggest that the developed video system is a valid, reliable, and trustworthy instrument for measuring velocity and derived variables accurately with practical implications for use by coaches and practitioners.

RESUMEN

BACKGROUND: Over the past decade, there has been an increasing secular trend in the number of studies on social media and health. OBJECTIVE: The purpose of this cross-sectional study was to examine the content and characteristics of TikTok videos that are related to an important aspect of community mitigation-the use of masks as a method for interrupting the transmission of SARS-CoV-2. METHODS: In total, 100 trending videos with the hashtag #WearAMask (ie, a campaign on TikTok), along with 32 videos that were posted by the World Health Organization (WHO) and involved masks in any way (ie, all related WHO videos at the time of this study), were included in our sample. We collected the metadata of each post, and created content categories based on fact sheets that were provided by the WHO and the US Centers for Disease Control and Prevention. We used these fact sheets to code the characteristics of mask use. RESULTS: Videos that were posted on TikTok and had the hashtag #WearAMask garnered almost 500 million views, and videos that were posted by the WHO garnered almost 57 million views. Although the ratio of the number of trending #WearAMask videos to the number of WHO videos was around 3:1, the #WearAMask videos received almost 10 times as many cumulative views as the WHO videos. In total, 68% (68/100) of the trending #WearAMask videos involved humor and garnered over 355 million cumulative views. However, only 9% (3/32) of the WHO videos involved humor. Furthermore, 27% (27/100) of the trending #WearAMask videos involved dance and garnered over 130 million cumulative views, whereas none of the WHO videos involved dance. CONCLUSIONS: This study is one of the first to describe how TikTok is being used to mitigate the community spread of COVID-19 by promoting mask use. Due to the platform's incredible reach, TikTok has great potential in conveying important public health messages to various segments of the population.

RESUMEN

INTRODUCTION/OBJECTIVE: The aim of this study is to analyze the influence of sour taste and cold temperature in the initiation of the pharyngeal swallow (IPS) and bolus location at pharyngeal swallow onset in individuals after stroke. METHODS: Cross-sectional prospective study. The study included 52 individuals with unilateral ischemic stroke. Each individual was assessed by videofluoroscopic swallowing study with 5ml of paste bolus offering four different stimuli (natural, cold, sour, and sour-cold). The individuals were divided into two groups according to the offer sequence. Group 1 (G1) - received a randomized sequence of stimuli (24 individuals), and Group 2 (G2) -the stimuli were offered in the following order: natural, cold, sour, and sour-cold(28 individuals). The IPS time and bolus location at pharyngeal swallow onset were analyzed. The bolus location at pharyngeal swallow onset was defined using six different levels. RESULTS: Individuals in G1 did not show a significant difference in IPS time between stimuli. However, individuals in G2 presented a significantly shorter IPS time with the sour and sour-cold stimuli than with natural or cold stimuli. The bolus location at pharyngeal swallow onset did not show significant difference between stimuli in both groups. On the other hand, in the G2 it was observed higher frequency of swallowing with sour-cold stimulus at level 1 (the bolus head was located in any region between the fauces pillar and the point where the tongue crosses the inferior border of the mandible). CONCLUSION: The sour and sour-cold stimuli influenced the IPS time when they were offered in a sequential order. Moreover, both the IPS time and bolus location at pharyngeal swallow onset were not influenced by the sour and sour cold-bolus when offered in a random sequence.
